What bits to replace when swapping R&P?
 

I tried searching, but did not find a solid answer.

I'm having my R&P replaced with a 3.6. While the work is being performed, what additional items in the diff should be replaced? Axle seals, side bearings, pinion seal, and/or pinion bearings? Or, do I leave things alone as long as they look good?

Thanks!

All of those are worth swapping out while you have the diff out if they have some age on them.

I did all the seals on mine. The axle shop that did the swap said the bearings were fine, so I didn't bother.
